Purpose: This vector dataset was constructed in order to serve as the topographic base map for a geologic map as a basis for understanding processes and volcano hazards involved in the eruptions of Medicine Lake volcano. Supplemental_Information: All the topographic base map information used to publish U.S. Geological Survey Scientific Investigations Map 2927 is contained in this digital publication. Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: 1978 Ending_Date: 2010 Currentness_Reference: The information in this report is the most up-to-date available at the time of publication.

Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was edited for a scale of 1:24,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:24,000 will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the database. Similarly, where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data. Acknowlegdement of the U.S. Geological Survey would be appreciated in products derived from these data.

Completeness_Report: The report is intended to describe completely the base map features of Medicine Lake volcano at 1:24,000 scale. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Accuracy of the topography is limited by the 1:24,000 source map materials and the precision of the scanning and registration of these materials. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: No vertical positional data recorded Process_Step: Process_Description: Stable base materials for twenty-seven U.S. Geological Survey 1:24,000-scale topographic quadrangles were scanned at 800 dpi, creating TIFF images. The TIFF images were converted to ArcInfo GRIDs that were georegistered to the proper spatial coordinates. The ArcInfo GRIDs were then vectorized using the GRIDLINE command and combined into one single vector base with the APPEND command. Georegistration, vectorization, and metadata creation by David W.
